Chennai Votes on What It Lives With Every Day

As Tamil Nadu gears up for its April 23 Assembly elections — with nominations opening March 30 and results expected May 4 — the loudest voices are not always those at press conferences. They belong to the resident welfare association secretary in Velachery who has been raising the same flooding complaint for five years. The daily-wage worker in Thiruvottiyur whose lungs have carried the cost of an industrial belt that never cleaned up after itself. The IT professional in Sholinganallur who commutes 90 minutes each way because the metro stopped short. The trader in T Nagar who watches his narrow street choke a little more each morning.

Tamil Nadu has a final voter list of 5.44 crore electors for 2026, with Chennai alone accounting for 28.30 lakh voters spread across 16 assembly constituencies. These are people shaped by very different urban experiences — some living in India’s newest IT suburbs, others in 19th-century port settlements with burst pipes and no storm drains. What unites them is the gap between what they were promised and what they received.

This report maps the key local issues across Chennai’s three broad zones — North, Central, and South — that are likely to shape voting behaviour on April 23, 2026. It draws on verified reporting, parliamentary data, and civil society documentation to build a street-level picture of what is driving the city’s electorate.

PART ONE: NORTH CHENNAI

Constituencies: Thiruvottiyur · Dr Radhakrishnan Nagar · Perambur · Kolathur · Thiru-Vi-Ka Nagar (SC) · Royapuram · Harbour

North Chennai is the oldest, densest, and most industrially burdened part of the city. Stretching from the fishing lanes of Royapuram and Kasimedu all the way northeast to Ennore and Kattupalli, this zone carries a triple burden: industrial pollution that has worsened over decades, chronic flooding from inadequate drainage, and urban poverty concentrated in tenements and resettlement colonies. It is also, politically, the most dramatic battlefield of 2026 — with actor Vijay’s TVK making its debut at Perambur, right next door to Chief Minister MK Stalin’s Kolathur stronghold.

1.1  Industrial Pollution: The Open Wound of Ennore and Thiruvottiyur

The industrial belt running from Manali through Thiruvottiyur to Ennore is home to two coal-fired power plants and their ash dumps, coal stacking yards, a 10.5 million tonne per year petroleum refinery, dozens of petrochemical units, fertiliser plants, and three large ports. Air, water, and soil in communities including Athipattu, Kattupalli village, Ennore fishing hamlets, and parts of Dr Radhakrishnan Nagar have borne the cumulative impact of this concentration for decades.

In December 2023, monsoon flooding in the area was accompanied by a significant oil spill. The floodwater carried oil into homes in coastal Thiruvottiyur and parts of Tondiarpet, causing skin conditions among residents. Months later, an ammonia gas leak from the Coromandel International Limited (CIL) fertiliser plant in Ennore created fresh alarm. As recently as January 2024, the North Chennai MP submitted a petition to the Union Minister for Environment, Forests and Climate Change urging the permanent closure of the CIL plant.

The proposed expansion of Kattupalli Port — from 24.65 million tonnes per annum to 320 MTPA — has drawn sustained resistance from fishing communities in Kattupalli village and surrounding coastal hamlets in the Thiruvottiyur constituency. Inland fishers link the expansion to deteriorating livelihoods in creeks and backwaters. These are not peripheral concerns. They are the daily reality for tens of thousands of voters in the Thiruvottiyur and Dr Radhakrishnan Nagar seats.

1.2  Kodungaiyur Dump Yard: A Constituency-Wide Grievance

The Kodungaiyur garbage dump yard — one of the largest in Chennai — sits at the junction of the Perambur-Kolathur belt. Residents from Kodungaiyur itself, as well as nearby sub-localities including MKB Nagar, parts of Perambur proper, and Villivakkam, have raised persistent concerns about odour, leachate contamination of groundwater, and vector-borne disease loads in surrounding streets.

No sitting MLA has thus far delivered a credible plan for the yard’s closure or scientifically managed remediation. This has contributed to a low-grade but durable anti-incumbency sentiment in Perambur — the very constituency Vijay has chosen for his electoral debut. With over 2.22 lakh voters — the highest of any Chennai Assembly segment — Perambur is a constituency where civic grievances accumulate over a large and politically aware voter base.

1.3  Flooding and Stormwater Drainage Across North Chennai

Across North Chennai — from Royapuram’s fishing colony lanes to the interior streets of Tondiarpet and Perambur — stormwater drainage work has been either delayed, incomplete, or has itself become a source of disruption. Residents in Perambur and Kolathur have repeatedly flagged that ongoing drain construction creates traffic bottlenecks on key roads during peak hours, while the drains themselves remain non-functional during heavy rain events.

In Royapuram and Harbour, the dense residential fabric of communities including Kasimedu, Basin Bridge, and Washermenpet means that even moderate rainfall causes waterlogging in low-lying streets. Paravar Christian fishing families in the coastal lanes of Royapuram have long sought upgraded housing, reliable drinking water supply, and compensation for losses caused by industrial discharges into the Buckingham Canal upstream.

1.4  Perambur as a Political Flashpoint: Vijay, PMK, and the DMK Machine

The decision by TVK chief Vijay to contest from Perambur has transformed this North Chennai seat into the single most-watched constituency of the 2026 elections. Perambur borders Kolathur, where Chief Minister MK Stalin is standing for re-election, making it a symbolic battleground. The NDA has allocated Perambur to the PMK rather than fielding the AIADMK directly — a calculation that could split the anti-DMK vote between the PMK and TVK.

For Vijay, the constituency’s profile — high voter count, mixed community composition, a significant working-class base, and accumulated civic frustrations around the Kodungaiyur dump yard and incomplete stormwater infrastructure — provides terrain where his promise of a ‘corruption-free administration by ordinary people’ can resonate. Whether that resonance converts to votes against an entrenched DMK organisation in its own heartland will be the defining contest of election night.

PART TWO: CENTRAL CHENNAI

Constituencies: Villivakkam · Egmore (SC) · Harbour · Chepauk-Thiruvallikeni · Thousand Lights · Anna Nagar

Central Chennai is the city’s historic, commercial, and institutional core. It contains the state legislature, the Marina waterfront, the University of Madras, and shopping corridors that draw buyers from across Tamil Nadu. It is also home to a volatile electoral mix — Egmore and Harbour are reserved Scheduled Caste seats with concentrated Dalit populations, Anna Nagar is a well-planned upper-middle-class suburb with high civic expectations, and Thousand Lights and Chepauk-Thiruvallikeni carry some of the most diverse and densely packed electorates in the state. All six Chennai Central constituencies will see direct DMK vs AIADMK clashes in 2026.

2.1  The Voter Roll Storm: Anna Nagar and Thousand Lights

One of the most contentious pre-election issues in Central Chennai is the dramatic fall in registered voters following the Election Commission’s Special Intensive Revision (SIR) process conducted in late 2025. Anna Nagar saw the highest deletion rate in the Chennai Central zone — 42% of voters removed from the rolls, with the total electorate dropping from 2.8 lakh to approximately 1.18 lakh. Villivakkam recorded a similar 42% drop. Thousand Lights lost 97,082 voters — a reduction of 41%.

Resident welfare associations in Anna Nagar — particularly in sub-localities such as Anna Nagar West Extension, MGR Nagar, and Shanthi Colony — have raised concerns about the deletion of bona fide resident voters, especially tenants and younger working adults who were not present during door-to-door verification. In Thousand Lights, which covers Nungambakkam, parts of Kodambakkam, and Kilpauk, the deletions have disrupted party-level voter mobilisation and raised questions about the process’s transparency.

2.2  Chepauk-Thiruvallikeni: The Deputy CM’s Home Turf Under the Microscope

Chepauk-Thiruvallikeni, where Deputy Chief Minister Udhayanidhi Stalin is seeking re-election, is one of Central Chennai’s most historically layered constituencies. It encompasses Triplicane — one of the city’s oldest and most densely populated Muslim-majority residential areas — alongside Royapettah, Chepauk, and parts of Mylapore’s northern fringe.

Local issues here include deteriorating infrastructure in the narrow tenement lanes of Triplicane, particularly around Wallajah Road, Pycrofts Road, and the Nawab’s Garden neighbourhood, where ageing water pipes, encroachments, and inadequate solid waste collection are persistent complaints. The constituency also covers parts of the Marina seafront, where beach erosion, unauthorised vendor clusters, and the state of public amenities have been raised in resident forums.

TVK has specifically fielded a challenger against Udhayanidhi here, adding a high-visibility layer to what is otherwise a deeply local contest about ward-level governance and civic quality in Triplicane’s back lanes.

2.3  Egmore and Harbour: Reserved Seats, Unreserved Problems

Both Egmore and Harbour are reserved constituencies for Scheduled Castes. Harbour — which has the lowest voter count in Chennai at 1,16,896 — includes the port-facing neighbourhoods of George Town, Burma Colony, and parts of Sowcarpet. Fire safety in heritage-era buildings, commercial congestion on the NSC Bose Road corridor, and the welfare of port and dock workers are standing concerns that surface every election cycle.

Egmore, which covers Chetpet, Pudupet, Kilpauk Garden, and the Central Station neighbourhood, faces the combined pressure of a large migrant and working-class population, inadequate pavements on arterial roads, and a near-total absence of usable green space. The constituency is also home to transit populations concentrated around the bus stand and railway station, whose needs are rarely factored into ward-level planning.

2.4  Anna Nagar and Villivakkam: Connectivity, Roads, and Metro Timelines

Anna Nagar, a consistent DMK stronghold won 9 out of 10 times since 1977, is facing a direct DMK-AIADMK contest in 2026 while TVK’s General Secretary N Anand (Bussy Anand) fights from the neighbouring T Nagar. Residents of sub-localities including Anna Nagar Tower Block, Shanthi Colony, and the 2nd and 6th Avenues have been raising demands around traffic signal rationalisation, speed breaker maintenance, and the metro phase 2 timeline for the Villivakkam-Anna Nagar corridor.

In Villivakkam, TVK’s Election Campaign General Secretary Aadhav Arjuna is the candidate, injecting political energy into hyperlocal conversations about road quality on Jawaharlal Nehru Salai feeder streets, open plots used as illegal dumps near Retteri, and the pace of stormwater drain completion along the Padi corridor.

PART THREE: SOUTH CHENNAI

Constituencies: Mylapore · Saidapet · Virugambakkam · T Nagar · Velachery · Sholinganallur · Thyagarayanagar · Alandur · Tambaram

South Chennai is the city’s most economically diverse zone — running from Mylapore’s Brahminical heritage quarter through the commercial heartland of T Nagar and Saidapet to the IT corridor of Sholinganallur and the expanding satellite belt of Tambaram. It is also where the sharpest contrasts in civic infrastructure are most visible: gleaming high-rises in Medavakkam and Perungudi standing metres from stormwater drains that have not been cleared in years.

3.1  Velachery and Pallikaranai: The Flooding That Refuses to Go Away

Few civic issues in Chennai have as much documented history and as little resolution as the flooding of Velachery. The Velachery Lake, which covered 255.8 acres according to a 1970 survey map, has dwindled to less than 55 acres — the rest claimed by construction, road-widening, and institutional encroachment. The Pallikaranai marshland, a Ramsar-adjacent wetland that once served as a natural sponge for southeast Chennai, has been progressively reduced by encroachments that include government agencies such as the Greater Chennai Corporation, Metro Water, and ELCOT.

The consequence is structural flooding in Velachery, Pallikaranai, Madipakkam, and Medavakkam during every major northeast monsoon. Residents in sub-localities including Vijayaraghava Nagar, Adambakkam streets off the 100 Feet Road, and parts of Nanmangalam report that despite multiple announcements of stormwater drain projects, implementation remains piecemeal and the flooding recurs. The loss of the Vijayanagaram bus terminus in Velachery — demolished in 2016 for a flyover and never replaced — adds a public transport deficit to the area’s unresolved list.

In 2021, Velachery was won by a Congress candidate under the DMK alliance by just 4,352 votes. With 2,11,691 registered voters — the second largest electorate in Chennai — and a voter base spanning heritage families and upwardly mobile apartment residents, Velachery is a classic swing seat where flooding grievances and infrastructure promises will carry unusual electoral weight.

3.2  Sholinganallur: OMR’s IT Workforce Left Waiting for Infrastructure

Sholinganallur has the largest voter base of any constituency in Tamil Nadu, with over 6 lakh registered voters. It covers the densest concentration of IT companies on the Old Mahabalipuram Road (OMR) corridor, taking in sub-localities including Perungudi, Kottivakkam, Karapakkam, Neelankarai, and the rapidly growing high-rise belt between Sholinganallur junction and Siruseri. Despite this economic footprint, civic infrastructure has consistently lagged behind population growth.

The most consistent complaints from Sholinganallur residents are about water supply. Many residential complexes in Karapakkam, Neelankarai, and the Kanathur stretch remain dependent on private tanker water, with Metro Water connections absent or insufficient. Monsoon flooding on the OMR service roads is a recurring annual event, with floodwater entering basement parking in apartment clusters along the Sholinganallur-Perungudi corridor.

The long-awaited metro rail extension to OMR remained incomplete through much of the electoral campaign period, with the MRTS extension from Velachery to St Thomas Mount only coming online in March 2026. For Sholinganallur commuters travelling north to the city core daily, the absence of mass transit for years has meant continued road congestion and long commutes. The AIADMK is directly contesting this seat in 2026, with a large and politically aware IT electorate as the prize.

3.3  T Nagar: Congestion, Courts, and a Neighbourhood Under Electoral Pressure

T Nagar is Tamil Nadu’s commercial spine. Ranganathan Street, Usman Road, and the surrounding lanes of Pondy Bazaar, Panagal Park, and Venkatnarayana Road generate enormous economic activity — but the infrastructure supporting that activity has not kept pace with demand.

Parking and pavement quality on commercial streets, solid waste management in and around the market zones, and the condition of service lanes in residential sub-localities such as Gopathy Narayana Chetty Road, Jayalakshmi Estates, and the colony streets off North Usman Road are persistent resident concerns. The T Nagar constituency was lost by the AIADMK by just 137 votes in 2021 — one of the closest contests in recent Chennai history — making it a seat the opposition regards as genuinely winnable.

This week, the Madras High Court directed the Geetham restaurant chain to cease using branding similar to that of Chennai’s iconic Sangeetha chain and pay over the profits earned during the disputed period. The case is a reminder of the commercial identity and property-law consciousness that runs through T Nagar’s voter culture. TVK has fielded its General Secretary N Anand here, framing it as an outsider challenge to the political duopoly.

3.4  Mylapore: BJP’s Direct Contest, Heritage Flooding, and Campus Safety

Mylapore is the seat where the BJP has been allocated a direct contest against the DMK by the NDA alliance — an acknowledgment of the party’s higher-caste voter base in a constituency that includes the Kapaleeshwarar Temple complex and elite residential streets around Dr Ranga Road, Luz Avenue, and R A Puram.

Local issues here range from the periodic flooding of the Kapali Temple tank that inundates surrounding streets including Luz Church Road and Dr Besant Road, to the chronic parking deficit on narrow residential roads in Abhiramapuram and Mandaveli, to noise and encroachment complaints along the Mylapore Festival corridor. With 1,94,731 voters and a high average civic awareness, Mylapore residents tend to hold candidates to exacting standards.

The Anna University sexual harassment case — which came to light this week with the arrest of professor Gnanavel Basu in Abiramapuram and four additional students coming forward — has added a campus safety and institutional accountability dimension to the pre-election political conversation in South Chennai. Women’s safety is emerging as a cross-constituency issue that no party can afford to treat as secondary.

3.5  Tambaram and the Periphery: Infrastructure Gap Across Corporation Limits

Tambaram is where South Chennai’s infrastructure inequality is most starkly visible. The Greater Chennai Corporation (GCC) limit ends at certain points south of Guindy and Alandur. Where Tambaram Municipal Corporation begins, civic quality changes noticeably. Residents of sub-localities including Chromepet, Pallavaram, Selaiyur, Mudichur, and Tambaram Sanatorium have consistently cited unpaved colony roads, non-functional street lighting, inadequate sewage connections, and the absence of neighbourhood parks as their primary election issues.

The Bengaluru-Chennai Expressway project — whose total cost has risen from Rs 7,811 crore to Rs 10,507 crore, a 34.5% escalation confirmed by parliamentary data — passes through the Kancheepuram-Sriperumbudur corridor near Tambaram’s periphery. The Arakkonam-Kancheepuram stretch has been stalled since May 2025 due to financial stress on the concessionaire. For voters in Tambaram, Alandur, and Pallavaram whose daily commute and property access depend on this road network, the delays and cost overruns are not abstract governance failures but concrete daily inconveniences.

What the Locality Wants from the Legislature

Across Chennai’s 28.30 lakh voters, the common thread running through the concerns of Kasimedu fishers, Velachery apartment-dwellers, Sholinganallur IT workers, and Triplicane tenement residents is not ideology. It is delivery. The question on April 23 is not which party has the better slogan but which candidate can be held to account for the broken road outside the house, the flood that enters the ground floor every November, and the stormwater drain begun two years ago that remains unfinished.

The DMK enters 2026 as the frontrunner in Chennai, with pre-poll surveys placing its city-wide vote share significantly ahead of the AIADMK and TVK. But the margins are tighter in specific seats than the statewide numbers suggest. In Velachery, T Nagar, and Virugambakkam, the DMK alliance won by narrow margins in 2021. In Perambur, a new entrant contests from a constituency whose civic discontents have been documented and unaddressed for years.

The Election Commission’s flying squads have already seized over Rs 4.7 crore in cash in Maduravoyal and Rs 77.29 crore worth of gold and silver in T Nagar in the days before nominations opened. This tells its own story: that the currency of Chennai’s elections is not only votes but also the perception that governance can be bought. The candidate who can credibly argue otherwise — in streets people actually live in, with problems they actually have — is the one who will find the city listening.
